Chicago-Latrobe 52480 Drill Bit
The Chicago-Latrobe 52480 is a Silver & Deming drill bit designed for drilling large diameter holes in metal. Its 118 degree point angle provides effective centring and cutting action for general purpose machining tasks. The 1/2 inch reduced shank allows the bit to be used in standard drill chucks with smaller capacity. It is suited for machinists and maintenance professionals requiring a reliable high speed steel cutting tool.
Upgrading from standard twist drills
This bit replaces the need for a drill press with a large capacity chuck when creating holes up to 1 1/4 inches in diameter. The jump is worth it when a machinist needs to drill large holes using a standard 1/2 inch chuck on a portable drill or bench press. The black oxide finish adds wear resistance compared to uncoated high speed steel bits. It is not for buyers who need a full 1 1/4 inch shank for heavy industrial rigidity or those requiring specialised point geometries for exotic alloys.
Fitting into a workshop setup
The reduced shank fits directly into any 1/2 inch drill chuck, freeing the user from needing a Morse taper adapter or oversized chuck. High speed steel construction handles standard steel and iron machining without the brittleness of carbide. The 118 degree point works with conventional drilling speeds and feeds. It requires a rigid setup and cutting fluid to achieve clean holes in thick material. It does not suit high volume production runs where carbide tooling would reduce cycle times.

Questions about this item
Will the 1/2 reduced shank fit my 1/2-inch drill chuck?
Yes, the 1/2 reduced shank is sized for a standard 1/2-inch chuck capacity.
How do I install the 118-degree point bit without it walking on hard steel?
Start with a centre punch mark and apply steady pressure at low RPM to engage the 118-degree point cleanly.
When should I replace the high-speed steel bit?
Replace it when the cutting lips show visible wear or the black oxide finish has worn off the flutes.
